While the present invention is shown applied to a commercial bottleVfilling machine in place of its twin bottle capping head, it will beunderstood that the same may be designed as an in` upper end of theshaft 11.

held against endwise movement in the bearing 21= by a collar 22belowsaid bearing bracket, and

and pair of lfixed upright guide posts 12. These guide posts 12 extendupward through the feed table 10 andare connected thereabove by upperand lower tie'members 13 and 14, respectively. The upper tie member 13is vertically adjustable onthe guide posts 112, for a purposethat willhereinafter appear, and rigidly .secured where adjusted on said posts byhand-screws which have threaded engagement with thetiefmember` 13 andimpinge against the guide posts l2. The

table 10 and is rigidly secured to the guide posts 12 by split clamping`collars 16 formed with said.:

tie member. The shaft 11,V which is `midwaybetween the two guide postsl`12 and parallel there-,-V g to, is mounted for endwise reciprocatorymovement in bearings formed with the tie members 13 and 14. For thepurpose `of vthiscase .it is lower tiemember 14 rests on the top of thefeed not thought necessary to illustrate the' driving Y connections forreciprocating the shaft 11.

A cross-head 17 is 'slidably mounted on the'4 guide posts l2 vand. has arecessed seat V18 for a twingcapping head, not shown, secured by' apair. of nut-equipped bolts 19 to said cross-head. ThisV cross-head 17is connected to the shaft 11 for relative longitudinal adjustment by along screw- Y' rod 20 which has threaded engagementwith'saidcross-head.` The upper end of the screw-rod' 20 .l

is turnably mounted in a bearing 21 fixed .on the Said screw-rod 20 isthe hubV of aA hand-crank`23V above said `bearing bracket and bywhich'hand-crank the screw-rod the hand-crank 23 are ,secured by pins to,the`-`V` screW-rod' 20. By operating the screw-rod 20 the capping lheadmay be raised or lowered and the cross-tie member 13 adjusted on theguide for instance,

of thiscase, it will not be' necessary to illustrate. f

From a broad view point the bottles X may be placed on the feed table 10in bottle capping positions by hand or otherwise.

Referring n'owin detail to the invention which includes twin cappingheads that are laterally spaced from eachother and each thereof includesa base 24 on which a blockk25 issecured by screws. 4The ltwin cappingheads are individually and detachably'secured to the'cross-head 17 byhaving formed therewith bearing brackets 26 mounted in the cross-headseat 18 and rigidly secured by the bolts 19 to the cross-head 17. Thesebolts 19 extend through horizontal slots [51 in the bearing brackets 26which permit common horizontal adjustment of the twin capping heads onthe cross-head 17. A long'tie-bolt .27, which f extends:throughvapertured lugs ionthe bear-ing brackets 26, -clamps said bearingbrackets together and prevents lateral separationu thereof.

Formed in each block 25 is an Youter cylindrical magazine 28, a centeror intermediatedie a stop that limits the lifting movement of thecylinder 29, and an inner cap-apply-ing'lcylinderi :the'idie'ring 39center the blanks Y as they are 30. The axes of the magazine28 and thetwo v cylinders 29 and 30 are alliin'the samewertical plane and theplanes of the twin capping'heads are parallel.

'asndateof"itsrends;San inter-'nal' annular-Stop ledge 53. The walls of? the passageway 52from the outer edgeof the stop ledge 53 diverge outwardlyand downwardly'and afford a bottle centering surface 54. The passageway 52, above thestop ledge 53, is of the same diameter as `the cap-applying cylinder 30.1

Within the cap-applying cylinder 30 is a reciprocatory bottle-aligningand clamping sleeve 55 held against rotation in said cylinder by a keyand keyway 56. The sleeve 55 normally rests on the stop ledge 53 "and isyieldingly held by a coiled spring 57 compressed between the top of thesleeve 55 and a screw-cap 58 which closes the upper end ofthe cylinder30. In the lower end of the sleeve 55l is an internal bottle-aligningand holding seat 59 arranged to receive the outer top portion of abottle and align the same with said sleeve and hold the bottle againstlateral movement in respect thereto.

Withinthe sleeve 55 is a'reciprocatory plunger 60 having at its axis anupwardly projecting stem 6l which works in -a seat therefore inthe cap58. A coiled spring 62, encircling the stem 61, is compressed betweenthe cap 58 and plunger 60, normally and yieldingly holds said plungerprojected.l A nut 63 applied to the stem 61 outward of the cap 58 isarranged to engage said `cap as a base of resistance and limit theprojecting movement of the plunger 60. The lower end portion of theplunger 60 is shaped to'enter the depressed central portion of the cap Zand engage the entire upper surface of the cap and press the same intothe neck of a bottle on the seat therefore in said neck and also pressits sanitary flange onto the top of a bottle.

The caps Zas they are formed and stripped from the dies 37 and 38 aresuccessively moved edgewise from theV cap-forming cylinder 29 through apassageway 64"in the wall of the block 25 between the cylinders 29 vand30, through a passageway 65 in the sleeve 55 and into said sleeve. Whenthe sleeve 55 is resting on the stop shoulder 53` its passageway 65 isin nal diameter same as the of the sleeve 55 is substantially theexternal diameter of the sanitary fiange of the'cap vZ and theengagement of said flange with the internal wall of the sleeve 55centers the cap in said sleeve and in respect to the bottle X.

An ejector bar 66 is cap Z from the cap-forming cylinder 29 to theycap-applying cylinderv 30. This ejector bar 66 extendstransversely over.the base 24 and'slidably rests thereon `for reciprocatory movement. Theunder side of the ejector. bar65 intermex4 diate of its endsis providedwith a notch ofv such size as to permit said bar to pass'over the posi'-tioning pins 43. This ejectorbar 66 above its notch is arranged toengage a cap Z at the edge of its sanitary flange and move the same inad- Vance thereof. l

Referring nowto the connections for reciprocating the ejector slide 33,the same'includes a pair of bell-cranks 67 pivoted at their elbows to apair of brackets 68 secured one to each side ofthe block 25. bell-cranks67 extend vertically downward, are relativelylong and connected by apair of horizontal links 69 to the sides of the cross-head The otherarms of thebell-cranks 67 are very short, extend horizontally awayfromthe ejector slide 33, are bifurcated and have formed on the upperprongs thereof, substantially verti- `,cal cam 4surfaces 70 and on thelower prongs provided forfmoving theV manner.

The depending arms of` theA thereof substantially horizontal camsurfaces 71,. Cooperating with each pair of cam surifaces .70 and 71 isa cam roller 72. The two cam` rollers 72 are journaled on a pair ofaxially aligned trunnions on the -lower end portions of the legs of ayoke 73 that transversely straddles the block 25. This yoke 73 iscarried by the stem 61 which extends through a bore at the center of thetransverse portion of said yoke.

A nut 74 applied to the stern 61 ,outward of the yoke 73 is arranged toengage said yoke and limit the upward movement of the yoke thereon. Thestem 61 above the nut 63 is reduced .in diameter to form a shoulder 75vand a coiled spring 76 encircling the stem 61 is compressed between saidshoulder and the under side of the transverse portion of the yoke 73..The purpose of the spring 76 is to cushion the action between the camrollers 72 and the bell-cranks f 67. The legs of the reciprocatoryyoke73 are held by anti-friction guide rollers 77 against the action of thecam rollers 72 on the cam the brackets 68 may beradjusted on the block100 25 toward or from the guide rollers 77. Ob-

viously, thevengagement of the cam rollers 72 with the cam surfaces 70and` 71 oscillates the bell-cranks 67 which, in turnpreciprocate theejector slide 33. l

The die 38 is reciprocated` by the following connections, actuated bythe capping head during its reciprocatory movement by the shaft 80. Avertical link A81-ispivoted at its upper v v l end to and betweenthe'levers 78 for horizontal ahgnment with the passageway 64.Y The1nterswinging movement parallel to saidzlevers and its lower endispivoted to a short heavy stem 82 on the die core 45. This stemV 82 hason its lower end a screw stud 83 which is screwed into the top,v of thedie core 45 at the axis thereof to connect the same. i

The'ejector bar 66 is reciprocated from the connectionswhich reciprocatethe die 38 by'a pair of cam rollers 84:` and a pair of bell-cranks 85.VSaid cam rollers 84 are journaled on the outer ends of a horizontalshaft 86 kwhich eX- tends transversely over said die. `This shaft 130bellecranks 85 are substantially identical withn135 the bell-cranks 67and arranged inthe samej Shortlinks 88 connect the lowerends` of thelong arms of the bell-'cranks 85 to the ends of the ejector bar 66. Inthe bifurcated short arms of the bell-cranks 85 are'upper cam surfaces89V and lower earn surfaces 90. The bell` cranks 85 arekpivoted to`bearing brackets 91 similar to the bearing brackets 62 and secured tothesides of the block25 in the same manner. From the above description `itis evident that it is necessary to placea bottle under lthe' cap.- pinghead and cause the sameto functionand when there is no bottleunder thecapping head `the ejector slide is not ;operatedto feedacap'l@ i145 rwhich center. the same'. y
